Sweet and Sour Chicken Stir Fry

Sweet and Sour Chicken Stir Fry – Better Than Takeout

If you love bold flavors, juicy chicken, and glossy, cling-to-every-bite sauces, then this Sweet and Sour Chicken Stir Fry is about to become your new weeknight obsession. This dish balances tangy acidity with gentle sweetness, all wrapped around tender pieces of chicken and crisp-tender bell peppers that deliver color, texture, and crunch. It cooks in under 20 minutes, uses pantry staples, and tastes like it came straight from your favorite Asian takeout restaurant—but fresher, cleaner, and better.

The magic lies in the sauce: a bold combination of rice vinegar, soy sauce, ketchup, and brown sugar thickened into a glossy glaze using cornstarch slurry. Every ingredient serves a purpose, every step builds flavor, and the result is irresistibly sticky, sweet, tangy, savory, and deeply satisfying.

Ingredients & Their Roles Explained

1 lb boneless chicken breast – The protein base; mild in flavor and perfect for absorbing sauce while staying juicy when cooked quickly at high heat.
1 red bell pepper – Adds natural sweetness, color, and antioxidants; stays crisp when stir-fried.
1 green bell pepper – Slightly bitter, earthy contrast that balances the sweet sauce and enhances depth.
1 tbsp vegetable oil – High smoke point oil ideal for stir frying without burning; helps brown the chicken.
1 tbsp sesame seeds (optional) – Nutty finishing garnish that adds aroma, visual appeal, and texture.
¼ cup rice vinegar – The tangy backbone of the sauce; brings bright acidity essential for classic sweet-and-sour balance.
¼ cup ketchup – Adds tomato sweetness, umami, color, and gentle acidity; also helps sauce cling to chicken.
2 tbsp soy sauce – Salty umami anchor that seasons the entire dish and balances sweetness.
2 tbsp brown sugar – Adds molasses depth and sweetness; melts smoothly into sauce creating shine and stickiness.
1 tbsp cornstarch – Thickening agent that transforms liquid into a glossy glaze that coats each ingredient evenly.
½ cup water – Adjusts sauce consistency and activates cornstarch for thickening.

Step-By-Step Instructions

Make the sweet and sour sauce: In a bowl, whisk together rice vinegar, soy sauce, ketchup, brown sugar, cornstarch, and water until completely smooth. This ensures the sauce thickens without clumping. Set aside.
Heat your pan: Place a large skillet or wok over medium-high heat and add vegetable oil. You want the pan hot enough to sear, not steam.
Sear the chicken: Add chicken pieces in a single layer. Cook 5–6 minutes, stirring occasionally, until golden and fully cooked. Browning builds flavor through caramelization.
Stir fry the peppers: Add red and green bell peppers. Stir continuously for 3–4 minutes until crisp-tender. This keeps color vibrant and texture firm.
Pour in the sauce: Add your prepared sauce and stir constantly for 2–3 minutes until thickened into a shiny glaze. The sauce should coat the chicken like lacquer.
Finish and serve: Remove from heat and sprinkle with sesame seeds if using. Serve immediately over rice or noodles.

Pro Tips for Perfect Results

1. Marinate the chicken for tenderness: Toss chicken with 1 tbsp soy sauce + 1 tsp cornstarch for 15–30 minutes. This creates a velvety bite known as the Chinese restaurant “velveting” technique.

2. Keep the pan HOT: Stir fry is all about high heat cooking to avoid soggy vegetables.

3. Don’t walk away once the sauce is added: Cornstarch activates fast—you must stir continuously to prevent lumps.

4. Want it saucier? Double the sauce for drizzling over rice—especially irresistible if you love extra glaze.

5. Customize your vegetables: Add pineapple chunks, onions, snap peas, or carrots for even more sweet-and-sour complexity.
